WEATHER STRIP...

Application led July 3, 1924. Serial No. 723,901.

vcitizen of the United States of America, a

` resident of the city of St. Louis, yin the clear, and eXactdescription,

y struction,

State of Missouri, have invented certain new and useful Improvements inWeather Strips, of which the following is a full,

reference being had to the accompanying drawing, forming a part of thisspecification.

This invention relates to improvements in weatherstrips, and the mainobject of the invention is to'produce a strong, simple and inexpensiveflexible weatherstrip having a neat appearance and provided with anenclosed resilient member which will force said weatherstrip into firmcontact with the elements with which lit is associated. r

lVith the foregoing and other objects in view, the invention comprisesthe novel concombination and arrangement of parts hereinafter morespecifically described and illustrated in the accompanyingldrawings,'wherein is shown the referred embodiment of the invention.owever, it is to be understood that the 'invention comprehends changes,variations and modifications which come within the scope of the claimshereunto appended.

Fig. I is an enlarged perspective of a fragment of my improvedweatherstrip.

Fig. II is an enlarged horizontal section I showing my improvedweatherstrip applied to a door.

Fig. III is a view similar to Fig. II, but showing the door andweatherstrip as they will appear when the door is in a warped condition.

Fig. IV is a fragmentary perspective showing a modified form of myinvention.

To illustrate the use of the new weatherstrip I have shown portions of adoor and the associated door framepequipped with a weatherstrip A. Aportion of a door is shownj at B, and C' designates a portion of theassociated door frame, the weatherstrip being secured to the door frame,as shown in Figs. II and III, and being' adapted to contact with thedoor as illustrated. Each gasket is provided with a longitudinalattaching flange D adapted to receive tacks l' or other suitableattaching devices, which may be inserted through the flange and driveninto the object to which the weatherstrip is applied.

The preferred form of the'infvention comrises an elongated body ofyielding packing 2r. which may be made of soft, fibrous cord, preferablyasbestos. The, body of packing is primarilycircular in cross section, assho-wn inFig. I, and it may be compressed-so that it will form aneffective seal. When the pressure which is causing the weatherstrip tobe flattened is relieved, lthe body of yielding packing 2 is of suchnature that it will tend to return to the substantially circular shapeshown in Fig. I.

The weatherstrip includes a strip of leX- ible, pliable material,preferably waterproof fabric, having a tubular portion 3 surrounding theelongated body of packing, outer flange portions 4 extending from oneside of the packing, and intermediate flange portions 5 foldedb-ackwardly and interposed be'- tween `said outer flange portions 4. Inthe preferred form 'o f the invention, the inter-l llange pprtions arein contact with the A posed inner faces of the outer ange portions 4,and there is a slight space between the oppositely disposed portions 5,the purpose of which will now be explained. Arranged within theweatherstrip A is a strip of resilient material 6, a portion of 'saidstrip being interposed between the backwardly folded flange portions 5and the remainder of said resilient strip extending from the flange D ofthe weatherstrip intothe interior of the tubular portion 3 thereof. Theresilient strip- 6 extends from end to end of the weatherstrip, assuggested by Fig. I. I prefer to form the strip 6 associated with one ofmy weatherstrips of celluloid or similar material which possesses acertain amount of resiliency, but it is to be understood that I do notlimit myself to any particular material but may use any materialresilient to function as desired. en I employ a resilient strip formedof celluloid or/similar material which may be perforated by a sewingneedle, I secure they which is sufficiently `li ht and a row of stitches7 is ,formed through the 'v flange elementscand resilient'.v strip atthe junction of the tubular portion 3 andthe kouter flange portions 4,elements and at the same time securely con fine the packing in saidtubular vportion 3. I also form a second row -.of "stitches 8v so as Vtounite saidv through said flangeportions and said resilient strip-in aline which is adjacent to the outer edge of the flange D.

When the device is manufactured the flange D is approximately radialto'the body of packing 2 and the resilient strip 6 is in alinement withsaid flange,r but owing to the flexibility of the strip of fabric A ahinge-like connection is formed at the lof my l which the stitches 7 sothat when the flange D is attached to a flat surface it may lietangential' to the body of the packing, as suggested by Fig. II. Thiswill resultin strip being deflected from its normal posi` tion to thepositions in which it is shown in Figs. II and III, and because of theresilient nature of said strip it is apparent that it will be placedunder a tension which. is always tending to return said strip Vto itsnormal position. This will have the efl'ect of forcing the tubularportion of the weatherstrip tightly against the elelnent with which itis associated, which element is, in the arrangement shown in' Figs. II

and III of the drawing, the door B.

It is plain in view of the foregoing that a weatherstrip made inaccordance with my invention will very effectually seal an opening suchas is found between doors and windows and their associated frames, forthe reason that the resilient strip 1n said.

weatherstrip 'will cause the flexible body thereof to adhere closely tothe element with weatherstrip -is associated, regardless of1rreg`ular1t1es in the surface of said element due to the warplngthereof.

c Fig. IV illustrates a modified form of myI invention in which thetubular portion 3 is provided with a single ply flange portion 5 whichextendsl outwardly from said tubular portion 3. 4 designates an outerflange portion which is folded backwardly in a manner to enclose saidsingle ply flange portion 5', the ledge of said outer flange portion '4being located on the underside of the flange adjacent to the tubularportion 3. Arranged within the weatherstrip illustrated 4in Fig. IV is aresilient strip 6 preferably of metal, such as thin steel or similarmaterial, said strip of material being interposed between the singleply'flange portion 5v and the upperportion of the folded flange portion4. It will be remembered that'the resilient strip 6 in thevpreferredform of my invention is held in place by means of stitches, but in themodified form invention illustrated in Fig. IV the resilient stripis-formed of metal and consequently it would be impossible to pass asewing needle through said strip to perform the stitchingpperation." Inthe modified form of my invention, therefore, I secure the flange"portions 4and 5' and the resilient strip 6 together by means of cement,there being a layer of-'oement between the upper the resilient section'of the flange portion 4 and thc top face of the strip 6, 'a second layerof cement between the lower face of the strip 6 and the top face of'theflange portion 5, and a layer of cement between the. lower face of theflange portion 5 andl the top facel of the lower section of theyflangeportion 4. In View of this arrangement, it is apparent that theflange portions 4 and 5 and the resilient strip 6 together.

To provide means for permitting tacks to be passed through the flange Dof the weatherstrip illustrated in Fig. IV, I provide said flange D withapertures 7.
